FERTILIZER-DRYING MACHINE.

SPECIFICATION forming part of Letters Patent N o. 726,120, dated'Aprl 21, 1903.

` Application nedllu'gnst 11,1902'. fsritrn'o. 119,285. (roman.)

To all whom it may concern:

Beit known that I,WILLIAM T. RIE, a citizen of the United States of America, residing at Kansas City, in thecounty of Jackson and scription of the invention, such as will en'-v able others'to make'and use the same, reference being had to the accompanying drawings, forming a part of this specification.

The object of my invention primarily is to remove thoroughly and cleanly the adhering substance-such as grease, slime, &c.'of the fertilizing material which collects upon the inner surface of the drying-chamber and prevents the transmission of heat to the mass to be dried; Second, to gage the position of the knife-edge in passing over the inner surface of the drying-chamber;v third, to impart a Steadiness to the driving-shaft.

Thev inventionconsists in the novel con, struction andcombination of parts, such as will be first fully described, and specifically pointed out in the claims.

In the drawings, Figure l is alongitudinal sectional view of asteam fertilizer-drying machine, a portion of one end of the chambers being broken away, showing the drivingshaft, the radial arms, and the vcleaningA knives, and showing the invention applied to the arms and knives. Fig. 2isasectional view of the fertilizer-machine, taken npon the line a; of Fig. l, showingthe driving-shaft, the radial arms, andthe invention applied theret0. Fig. 3 is a detail'front view, enlarged, of the upper end portionof one ofthe radial arms, showing a portion of the adjustablel slotted knife-blade, the spring, the retainingplate, the slot for the adjustable roller-carrying arms, and the bolt-head. Fig. 4 is a detail rear View of the upper end of the radial arm and a portion of the knife-blade opposite to that seen in Fig. 3,x showing the spring and adjustable rollers. Fig. 5is a detail side view ofthe upper end portion of the radialarm, showing the knife-y blade and spring in section lupon the line a; of'Fig. 3, also showing the adjustable roller. Fig. 6 is a detail sectional view of the knife-blade,

taken on theY line yy of Fig. 4, showing the roller and the adjusting roller-carrying arms or brackets.

' Similar letters of reference indicate corresponding parts in all the figures of the drawings.

Referring to the drawings, A represents a Vcylindrical shell or case of suitable dimensions arranged horizout-ally in position and which forms' the receptacle for the fertilizer material. Upon the end of the cylindrical sides a of the shell A are flanges a', bolted thereto upon 'the outer surface of the ends and thence bent inwardlyand bolted to the circular end plate B. The outer ends of the plate B extend a short distance' beyond the lines of the outer surface of the side a of case A and are bent at right' angles and extended a short distance in an outward direcltion, forming an annular liange b, to which are bolted the ends of a cylindrical shell C concentric with the shell A, and between which shells is formed a steam-circulating space or chamberjc. The shells A'and C are 'supported by the braced upwardly-extending benches D at each end. Y

Connected with the outer shell C is a steamsupply chamber E, which communicates with the chamber c and which is provided with a steam-supply opening e.

F represents the hopper,leading to the shell A, within which the material to be dried is supplied.

y Extending longitudinally through the shell A and the end B of the said shell is-afrotary shaft Gr, upon the outer end of which is a beltpulley g. Upon the shaft G, within the rcceptacle A, are radial arms HH, extending in'an opposite direction to each other and in pairs, said pairs being arranged'a short distance apart. The outer ends ofthe arms H H extend to aposition a short'dstancefrom the inner side of the shell A, the inner ends of each arm H being curved inwardly to extend over one-half the circu Inference of the shaft G and provided with lateral'flanges h2 h2, which are bolted tolike anges upon the inner end of an oppositely-'extended arm. In the upper end of each varm H' and 'forward edge is a notch h3, extending inwardly an equal distance to the thickness of the knifeblade I, which is employed to remove the adhering substance from the shell, and downwardly about one-third the distance greater than the width of said blade is a shoulder h4. Within the said notches upon the ends of two of the radial arms, extending in the same direction, is arranged the blade I, which extends a short distance in length beyond the lines of the outer sides of said arms and in which blade opposite the arms H are slots t' t'. Within the slot h3, upon each arm and bearing upon the shoulder 7L4,is an elliptical spring K, theends of which are extended outwardly in opposite directions from the arm H and curved upwardly and at 7a are slightly curved downwardly and bear upon the lower edge t" of the blade I. The cleaningpart of the blade I is beveled or inclined to an edge "i2, extending from a position near the line of the end of the arm H forwardly and upwardly. Upon the outer surface of the blade I is a narrow guide-plate M, the lower end of which plate is secured to the forward side of the arm H by the screw m at a point a short distance below the shoulder h4. The upper end of the plate M extends a short distance above the slot 'L' in the knife-blade I, and in which blade opposite the slot is an opening m2, through which extends one end of a bolt N, upon one end of which is a head n, the other end of which bolt is screw-threaded and is extended through the arm H and a short distance beyond the rear side of said arm, and upon said end is a nut n' and a jam-nut n2, the plate M being held by the screw m and bolt N in such a position as to permit the blade I to move adjustably in the guides.

In the blade I, at a point a short distance inwardly from each arm, are the vertical slots 3 3, arranged a short distance apart and parallel with each other. Upon the rear side of the blade is a movable plate O, narrow in width, and upon each end and extending from the line of the upper edge are the outwardlyextending curved arms o o, in the outer ends of which arms is vjournaled a guide-roller 02. Through the plate O extend the adjustingbolts o3, which are screw-threaded and said ends extended through the slots is in the blade I, and upon the ends of said bolts are the nuts o4. These rollers are arranged in pairs upon each blade, and the periphery of each roller extends beyond the ends of the arms H H and bears upon the inner surface of the shell A of the machine.

The series of arms H H are arranged upon the shaft G and carry the blades I, so as to extend at different angles from the shaft, the shaftbeing strengthened by truss-rodsg g, extending through the ends of radial arms g2 g2.

In operation the Waste animal matter, such as is known as refuse in packing-houses, and also bones are placed within the shell A and dry steam supplied to the chamber c through the steam-chamber E, and this heat extracts the moisture from the mass and also reduces the same to a granular condition, a certain per cent. adhering to the inner side of the shell A. Power being applied to the shaft G through the band-pulley g, the arms H H are caused to rotate, the edges t? of the blades coming yieldingly in contact with the accumulation in the inner side of the shell A and removes the same, which falls tothe bottom of the shell. During the passage of the blades I I in their circle of rotation the rollers n2 bear against the shell, and the degree of contact is made greater or less as the plate 0 is adjusted to or from the direction of the shell. The position of the rollers n2 in such adjustment also fixes adjustably the position of the edge 2 of the blade I and enables the edge to take the matter cleanly from the shell without contact therewith, and this adjustment may be in degrees as the occasion requires. The rollers also act to impart steadiness to the shaft G, which from the necessary length is somewhat flexible and keeps the blades I I in a parallel position with the inner surface of the shell.

The invention is applicable to all stirringreceptacles and for such as are used in congealing iiuids.

Such modifications of the invention may be employed as are within the scope of the invention.

Having fully described my invention, what I now claim as new, and desire to secure by Letters Patent, is-
